The sparsity parameter for clusters of galaxies is obtained in the context of [Formula: see text]-gravity. It is shown that the theoretical estimated values are within the reported error limits of the measured data. Thus, in the future the sparsity parameter can serve as an informative new test to detect the discrepancy between General Relativity and [Formula: see text]-gravity.
